Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] A kind of decomposition facility that uses biomass to solve the exhaust gas of rural domestic waste composting, such as figure 1 , 2 As shown, the decomposition facilities include:

[0022] A compost bin 6, in which a leachate collection pipe 7 is arranged, on which biomass treatment exhaust pipes 1, 2, 3, 4 are arranged;

[0023] A leachate collection tank 9 , the leachate collection pipe 7 communicates with the leachate collection tank 9 .

[0024] Fans 8 are provided on the biomass treatment exhaust pipes 1, 2, 3, and 4.

[0025] The width of the compost bin 6 is 3-6 meters, the height is 1.5-2.0 meters, and the length is 50-80 meters. It can lie about 0.8 meters underground.

[0026] The semi-underground has good sealing performance, which is convenient for composting, fermentation and heat preservation. The fermentation gas is at a natural vertical height,...

Abstract

The invention discloses a decomposition device for treating rural domestic waste composting waste gas with biomass, which belongs to the technical field of agricultural waste utilization. The decomposition device comprises: a composting barn in which a leachate collecting pipe is disposed, and on which a biomass processing exhaust pipe is disposed; a leachate collecting pool which is communicated with the leachate collecting pipe. The decomposition device of the invention performs aerobic composting of rural solid waste; the composting temperature is easy to insulate and control; and the waste gas generated during the composting process is processed by using biomass corn cores and straw cores as special gas adsorption materials. The leachate is collected and sprayed back during the composting process, which can not only ensure the water content of the compost, but also realize zero discharge of waste water; the device can perform positive or negative pressure adjustment of the gas in the barn at any time, makes full use of the existing rural biomass resources, and can effectively purify peculiar smell generated by the compost.

Description

technical field [0001] The invention belongs to the technical field of agricultural waste utilization, and in particular relates to a decomposition facility for solving rural domestic waste composting waste gas by utilizing biomass. Background technique [0002] The composition and amount of domestic waste in rural areas change accordingly with the rapid development of the rural economy and the improvement of living standards. However, most villages in rural areas do not have standard waste disposal facilities. At the same time, sanitary landfills, high-temperature composting Restricted by local economic development conditions, it is difficult to promote and apply them in rural areas. At present, waste pits and ponds are still used as simple landfills. In some villages, domestic waste is not treated at all, and it is randomly piled outside the village and on roads. Rivers and rivers, and cannot be covered in time, resulting in serious secondary pollution. With the full deve...
